As the world shifts towards renewable energy, moving on from fossil fuels, but at the same time relying on ever more energy-gobbling devices, there is a fast-growing need for larger high-performance batteries. Lithium-ion ...

Many mobile devices are powered by lithium-ion batteries, which could be smaller, lighter, safer and more efficient if the liquid electrolytes they contain were replaced by solids. A promising candidate for a solid-state ...

Members of the D. V. Skobeltsyn Institute of Nuclear Physic and colleagues from the Faculty of Chemistry of the Lomonosov Moscow State University have developed a new silicon- and germanium-based material that could significantly ...

Silicon – the second most abundant element in the earth's crust – shows great promise in Li-ion batteries, according to new research from the University of Eastern Finland. By replacing graphite anodes with silicon, it ...

While lithium-ion batteries, widely used in mobile devices from cell phones to laptops, have one of the longest lifespans of commercial batteries today, they also have been behind a number of recent meltdowns and fires due ...

Magnesium batteries offer promise for safely powering modern life—unlike traditional lithium ion batteries, they are not flammable or subject to exploding—but their ability to store energy has been limited.

Most of the lithium used to make the lithium-ion batteries that power modern electronics comes from Australia and Chile. But Stanford scientists say there are large deposits in sources right here in America: supervolcanoes.

Battery researchers agree that one of the most promising possibilities for future battery technology is the lithium-air (or lithium-oxygen) battery, which could provide three times as much power for a given weight as today's ...

Lithium-air batteries produce power from air, and are often called lithium-oxygen batteries. They are much lighter than lithium-ion batteries due to higher energy density. Lithium-air batteries have applications including ...

Chlorophyll, blood, and vitamin B12 are all based on the porphyrin molecule. But porphyrin can also be used as an electrode material where it speeds up the charging process of rechargeable batteries. In the Angewandte Chemie ...
